Features

Previously, D-rings were assembled onto die-cast or forged components. However, to achieve compactness, cost reduction, and improved responsiveness, they have been replaced by BPS (Bonded Piston Seal) or BCS (Bonded Clutch Seal).

 

  • Achieved a more compact design compared to conventional methods.
  • Reduces costs.
  • Improves gear shifting responsiveness.
